Application
DEET and icaridin are the most effective insect repellents available.DEET is effective against a variety of invertebrates, including ticks, flies, mosquitos, and some parasitic worms.
A 2018 systematic review found no consistent performance difference between DEET and icaridin in field studies and concluded that they are equally preferred mosquito repellents, noting that 50% DEET offers longer protection but is not available in some countries.
